Pay with Bitcoin (BTC)

Pay any U.CASH merchant with Bitcoin. Your BTC settles final and direct from your wallet, with low fees and no chargebacks.

Why pay with Bitcoin

Crypto payments are final, global, and cheap. Bitcoin is a strong way to pay merchants directly.

No chargebacks

BTC payments are final on-chain. No card-style disputes clawing funds back weeks later.

Borderless

Pay any U.CASH merchant worldwide. No blocked regions, no currency conversion holds.

Low fees

Network fees instead of card processing percentages, especially on efficient chains.

Private by default

No card number to hand over. You sign a transaction from your own wallet.

Pay by name

Send to a web3 name (ENS, Unstoppable Domains, FIO) instead of a long address.

Fast settlement

Merchants see your payment confirm quickly, then release goods or services.

Before you start

Getting started takes a wallet and an address. The wallet needs to hold Bitcoin and a little BTC for gas on its chain; the address is where the output lands, raw hex or a resolvable web3 name both work. From there the flow is preview-first: what leaves, what arrives, the fee, and the network cost all sit on one screen before a signature happens. Keys never leave your side at any point, and the only thing the wallet ever signs is the exact transaction you read.

Fees and settlement

The cost picture is two lines. The platform side is a flat 0.50% all-in on the swap, quoted before you sign, with no spread and no routing cut behind it. The network side is gas paid in BTC, settling with about 10 min blocks on Proof-of-Work (SHA-256), which the preview itemizes per leg. Settlement is on-chain to the address you chose: 1 confirmation (fast), 3 (standard) on this asset, after which the balance is spendable and non-custodial in the fullest sense, yours to move with no platform in the path.

Underneath, an instant integration executes the trade with all-or-nothing semantics: partial fills do not exist here, and a route unable to meet the bounds you approved reverts the whole transaction rather than settling something worse. Your exposure window between legs is therefore zero, the only cost of a failed attempt is its gas, and re-quoting is a click.
